Specification of Letters Eatent.

Patented Jan. 22, 1907.

To all whom, it may concerni Be it known that we, OCTAVE AUBE and LOUISMARcELLIN TREMBLAY, subjects of the King of Great Britain, residing inthe city and district of Montreal, in the Province of Quebec, Canada,have invented certain new and useful Improvements in Smoke-Consumers;and we do hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and. use the same.

This invention relates to smokeconsumers.

The object of the invention is to provide means for automaticallyturning on a blast of steam into the combustion-chamber of a boiler whenthe door thereof is opened.

- A further object is to automatically open the draft-door of thecombustionchamber when the steam is turned on.

A further object is to provide means for regulating the length of timewhich the blast of steam will continue.

A further object is to provide means for automatically cutting off theblast of steam.

A further object is to provide means when the period of the blast ofsteam is once established to make the blast extend over the same periodfrom the time the door is opened until the apparatus is again adjusted;and the invention consists of the construction, combination, andarrangement of parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, isillustrated one form of embodiment of the invention, in which drawingssimilar reference characters designate corresponding parts, and inwhich- Figure 1 is a frontelevation of a portion of a boiler, showingthe application of the invention. Fig. 2 is a front elevation of theboiler, showing the door of the combustionchamber open and showing theapplication of the invention. Fig. 3 is a horizontal sec-- tion on line3 3 of Fig. 1. Fig. 4 is a vertical section on line 4 4 of Fig. 2. Fig.5 is a vertical section on line 5 5 of Fig. 4. Fig. 6 is a horizontalsection on line 6 6 of Fig. 4. Fig. 7 is a fragmentary detail in plan ofa valve used in the invention. Fig. 8 is a irag'- mentary detail in planof a screw-threaded rod adapted for use as a valve in the invention.Fig. 9 is a vertical section through the door of a portion of the frontplate of the combustion-chamber. Fig. 10 1s a vertical section throughan injector-nozzle used in the invention. Fig. 11 is an elevation of theinjector-nozzle used in the invention. Fig. 12 is a fragmentary detail,in rear elevation, of the regulating-lever, its su porting pintle beingshown in section; and ig. 13 is a vertical section on line 13 13 of Fig.12.

Referring to the drawings, 1 designates the front plate of acombustion-chamber of a boiler. The front plate 1 is provided with asuitable opening, over which is disposed a plate 2, secured in positionin any suitable way and provided with the usual fuel-opening. Disposedover the fuel-opening in the plate 2 is a door 3, provided with adraftopening 4, which opening is covered by a draft-door 5.

The door 3 is provided with lugs 7, disposed on the lugs 8, formed onthe plate 2, said lugs being pivotally connected by means of the pintle9. Disposed on the lower lug 7 is an eccentric 10, to which is connecteda rod 11, pivotally connected at 12 to a valverod 13.

Secured on the plate 2, adjacent the end of the valve-rod 13, is anextension 14, provided with a horizontal chamber 15 on its side adjacentthe plate 2. chamber 15 is a valve 16, which is connected to thevalve-rod 13. The valve 16 is provided with the circumferential grooves17 17 Leading from the chamber 15 are ducts 18 18 connecting thevalve-chamber 15 with an upper chamber 19 in the upper part of thecasing 14 on its side nearest the plate 2;

Communicating with and leading from the chamber 19 is a supply-pipe 20in connection with a suitable source of water and provided with a valve21, adapted to regulate the water-supply.

Leading upward from the chamber 15 is a port 22, communicating with theupper part of a valve-chamber 22 the lower end of the port22 beingL-shaped in vertical section, as shown in dotted lines in Fig. 5, sothat the Disposed in the into the combustion-chamber.

lower portion of said port is in communication with the circumferentialgroove 17 Disposed in the pistonchamber 22 is a piston 23 to which isconnected a rod 24, a suitable packin 25 being disposed around the rodwhere it passes through the casing 1.4.

Leading from the chamber 15 is a port 26, which communicates with thelower portion of the chamber 22', the upper portion of said port beingL-shaped in vertical section, as best shown in dotted lines in Fig. 5.

' Leading from the lower part of the chamber 15 is a duct 27, whichcommunicates with an exhaust-chamber 28, which exhaustchamber has anexhaust-pipe 29 leading therefrom.

The casing is provided with suitable eX- haust-ports 30, leading fromthe opposite ends of the chamber 15 to the exhaust-chamber 28, whichducts are adapted to carry off any water which accumulates in thechamber 15 at the ends of the valve 16.

Leading from the lower part of the chamber 15 is a passage 31,which isconnected to the exhaust-chamber 28 by means of the passage 31 whichlatter is adapted to be closed by the pointed end of the screw-threadedrod 32, which serves as a valve, the outer end of said rod beingprovided with a hand- 1 wheel 33.

Pivotally connected to the upper end of the rod 24, which is connectedto the piston 23, is a link 34, its opposite end being pivotallyconnected to a lever 35, which lever is pivoted at 36 to the plate 2.Secured on the lever 35 is an angle-iron 37. Connected to the end of thelever 35 is a flexible member 38, preferably a chain, the opposite endof which is connected to the draft-door 5, which is hinged at 39 to thefuel-door 3.

Disposed adjacent the front of the plate 1 above the door 3 is asteam-pipe 40, one end of which is connected to a suitable source ofsupply and the other end of which extends Disposed on the pipe 40 in thepath of movement of the angle-iron 37 on the lever 35 is a valve 41 ofany suitable construction, which is adapted to be turned by the movementof the angle- 1ron.

Secured on the end of the steam-pipe which communicates with thecombustionchamber, is a nozzle 42, having the screwthreaded plugs 43,which may be removed for the purpose of cleaning the nozzle toremove theaccumulations left by the steam, and provided with a line ofperforations44.

The door 3 being in closed position, as shown in Fig. 1, and the piston23 being adjacent the upper part of the casing 14, the

door 3 may be opened on its hinges, and theeccentric 10 and itsconnections cause the valve 1 6 to move to the position shown in Fig. 5.When in this position, water in the chamber 19 will pass through theduct '18, around through the circumferential groove 17 and thencethrough the port 22 to the chamber 22* and force the piston 23 downwardin the direction indicated by the arrows in Fig. 4. This movement of thepiston causes a downward movement of the piston-rod 24 and theconsequent rocking of the lever 35 to the position shown in Fig. 2. Therocking of the lever 35 by means of the angle-iron 37 actuates the valve41 and turns on a blast of steam through the nozzle 44 into thecombustion-chamben The blast of steam will continue until the lever 35is actuated back to the position shown in Fig. 1. In order ,that thepiston 23 may ascend to rock the lever back to the normal position, thewater above the piston must pass back through the port 22 to the chamber15. In the meantime, the door 3 having been closed, the rod 11 isactuated to throw the valve 16 so that the circumferential groove 17registers with the passage 31, through which the water may escape intothe passage 31 and thence to the exhaust-ch amber 28 and out through theexhaust-pipe 29. The length of the period of the blast will be thusproportioned to the size of the passage 31. 32 so that its pointed endcloses the passages 31 and 31 the length of the blast may be regulated.The valve 16 having been actuated so that the circumferential groove 17a registers with the passage 31, the circumferential groove 17 willregister with the duct 18, so that the passage of water from the chamber19 will be through the duct 18, around the circumferential groove 1.7,and through the port 26 to the bottom part of the casing 1.4, beneaththe piston 23, which will be actuated upward thereby. The door beingagain opened, the piston 23 will be actuated downward, the waterthereunder being exhausted through the port 26, the circumferentialgroove 17, and the duct 27 to the exhaust-chamber 28 and from thence outthrough the exhaust-pipe 29. The rod 32 having once been adjusted for acertainlength of blast, no further adjustment is necessary, and the sameperiod of time will be consumed for each blast of steam until the rod isagain adjusted.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is
